Surface Fractal Parallel Plate Models for Micropore Structures of Active Carbon

Ozone Treatment of Coal- and Coffee Grounds-Based Active Carbons: Water Vapor Adsorption and Surface Fractal Micropores

“…On the other hand, in the case of D s Ͻ 2 (D v Ͻ 3), the micropore volume is also the sum of respective micropore units whose flat micropore walls are running parallel with each other with variable gaps of molecular dimensions as described previously (23,24). The micropore volumes are increased with the increase in the molar volumes of the adsorbate molecules as shown in Fig.…”

“…The adsorption potentials of dispersion forces are strongly enhanced in micropores because of the overlap of the fields from the opposite micropore walls; therefore, micropores are the basic factor in adsorption (28). The micropore volume is the total volume of the respective micropore units (23,24), which is made up of the space between opposite pore walls with L Յ 2 nm, and the total micropore volume can be estimated from the DR (16) Table 1.…”

“…Here, for the analysis of micropore structures, the theory of volume filling of micropores (4) and the parallel plate models of micropore structures (15,(22)(23)(24) were adopted. Applicable here is the equation…”
